摘要： A speaker device includes a speaker diaphragm composed of a selected acoustic diaphragm material whose acoustic loss coefficient (tan &dgr;) is more than 0.02 in a frequency band over 20 kHz, and including a dome positioned at the center of the diaphragm and shaped to be substantially arcuate in its cross section, with an edge positioned outside the dome and formed integrally therewith through a link; and a conductive one-turn ring inserted into a magnetic gap and bonded fixedly, at one end thereof, to the link between the dome and the edge of the speaker diaphragm. In this device, signals of a frequency band over 20 kHz are reproduced by utilizing the split vibrations of the speaker diaphragm.

摘要： An acoustic diaphragm employed in a speaker or the like and a method for producing the acoustic diaphragm are disclosed. A diaphragm substrate is a diaphragm exhibiting air permeability such as a paper diaphragm. The substrate is processed with filling by microfibrilated pulp. For filling, the substrate is immersed in the liquid dispersion of the microfibrilated pulp and the pulp is deposited on the substrate under suction. When the microfibrilated pulp is deposited on the substrate under suction, any voids present in the substrate are closed by the microfibrilated pulp so that air tightness is improved without lowering the sound quality or detracting from desirable properties of the diaphragm, such as low density, high toughness and low losses.
